Hi every one, I hope this is where I can post this question, (I'm new here). This spring I have received a young liner of Acer Palmatum 'Beni maiko'. I repotted it as normal,(I have about 15 other various potted A.P.'s) It leafed-out beautifully then all the new growth wilted. All the plants are together in a protective cove of my house. None of the other plant have a problem, infact this year they're more beautiful. I never had anything like this happened with my maples. Roses yes, I think due to refrigeration storage. Is this a bad graft? Should I ask the grower for a replacment or is this a situation where I swallow my loses? Any suggestions would be greatly appreciated.
